To all whom it may romero:

Be it known lthat l', SAMUEL Mimmo, o citizen of the United States, residing at Chi "ergo, in the county of Cook ood Stato o'l? Limoio, have inventori certoin new und oso fui vimproremonte in Dump-WVugons, of which the following is o specification.

My invention relates to improvements in dump Wagons.

@ne o the salient objecte of my invention is to provide :fr dump wagon which 'will dump that portion of its lood cootoined in the bed, in front of the hind 'wiloeis0 Tiri o cent1-ol windrow, so :is not be in the path of the said wheels of the Wagon when it movefi forward.

Another object of my invention to pro vde e wagon bed of such chorocter that the ortiono thereof may be dumped 'when the moors, ocnted in the bot tom wail or ioor of the bed, oro opened.

@ther ond further objects of my invention will become readily understood by oeroons: skiiied in the ort upon consideration of the following,description token in conjunction with the drawings, wherein:m

Figure l is o side elevfvtoo of my Wagon; Fig. 2 is a. View of the bottom thereof; Fig 3 is o. iongitudinai sect-ion of the front end of the wogori bed; :rmi Fig. o top plan View thereoi in oil the firms tile some reference chorefsters ere userv to indicate similar ports.

in the exetoplil'eotion illustrated l() indictates the bed, 1l the raised seat extension,

und .i2 the removable side Wings. The bottom iframe of the 'ood consists; of side members 13 and 14, and tronsvorso connecting eiiis 15, 16, ond 17. The frontend woll 18, of the bed] extends forwordiylot un ongle from the S111 i7 to a point 19, new' the seat The sitio 'wolle .320 :rml 21, preferably, extend in vor-tieni plaines up wordiy 'from the Hoor of the bed, and the removable Wings 12 ma be flared so :is to increase the capacity ai? the bed above the upward limits of the Sides 2O und 2L It wiii be observed that the Sent extension 11. is

raised above the moin ood to provide mmm for the front Whee sind oppurtewzni; ports E22, solid wheels being.; supported ou the front axle o" under the soot extension 11.

v A. hand operated arm 4&9 is similarly journelecl on the shaft 1li, on the outside of the Seat extension. This arm 19, is connected to the erm 47, by ineens of a bar 50. The

bar 5G posses through a slot 51 in the sicle .member 2l of the hell. lt is now clearly op parent that when the hand. lever i9 oscilleted the lever 47, can-ying the pawl 418, is similarly osoillated and the eli-uni il is thereby rotated.

In order that each i'eciproczition of the lever 4C!) may beell'octive a, retaining pswl 52, for engagement "with the ratchet vlieol l-t, is pivoterl to the lioor 35, as at The release level' 54, is pivoted to the vertical woll o the seat-extension as et and is downtumerl on the inteioi oli the seat eX- tension :is 57. linl 58 Connects the pavo. r32, and the clownturoetl, portion 57 of the' foot lever es at 59 rund {30,entl a spring 6l. yielsflingly holds the puwl wit-ii yits upper free end in e'lgagemcnt with the teeth of the-ratchet, wheel 4G. Now it is opposent u I that. when the lover is oseillotedv and the drum 14 is rotated to the extent of one tooth. of the Wheel +16 by on oscillation of lever 49 the retaining powl 52 will engage the 'teeth of thev wheel 4G :incl holol the drum Ll-/l -in the position in which it is placed by the oscillation oi the lever 9. me;y then be ieturnecland the operation repeated. v"fiheie it is'cl sited to release t oium 44C from the powl. plus muy be applied to the foro @ncl of the loot lever 54e, thereby pushing paul out of engagement with the teeth ol the ratchet. .vlieel 4G. Two chains or ropes GQ sind GQ" :iro Wouml upon the drum lll.

A retaining pawl 73, is pivoteel :isst 7e',- antl is uptuined es at 75 to ijiiovitle e t" lever. A. spring serves to yielding tuin-the piu-Nl is association with the te the iatchet Wheel '70 so that when the 4J. is Viotetel 'by means of the osoilh lever 7l, it retained in the position tn t, it has been thus placed hy the ieoipioootion of the lever 71, in s menne? sini-iler to the ,operation of the lever t9 heretofore described. The-topes o1 olif-ins 8l and 8l may be Womcl upon the respective Cimino 42 and 43. Chains 8l :incl Sl are siiniloilyoonneoted to the door 533, like being indicated oil the row by the same numerals distinguished by o xpomeiuJ prime The 8l posses through the interior of soot, extension ll, through the side Wall 21, along the outside of the side Weill 2l, through o staple .82, over a pulley 83, and at its enti is seou-i'eclfto e projection 84, located at the extreme enel of the door 33. Now it is manifest. tias-.t when' the chains oiropes 8l end 8l slack: the door will fell oi' open downwecll of own weight, ont' the Weight of the load and that when it has openefl to its fullest. extent it may loe again closed, by ineens of the operation of the lever 71'., conveniently located at the right han@ Sitio' o? the divei.

The door is raised by the ineens desciibed. equally from each of its free enflswitliout warping or twis ingand the application of, the power to lift the dooris uniform anti eliicient.

lWhile l have referred to the. nnecting mediums between the cloos and the Ineens for lifting them es ropes, it is o 'tient 'that wire cable or chains may h emloyecl this purpose, or :my other 'fie t le aoiezeoting medium o1 the desired s bility.,

While lv have herein described o `single embodiment of my invention for the purposes of complete disclosure, it is evident that many changes may he mede therein Without departing from the spirit of my invention and Within the scope ol the appended claims.

`Whet l claim is:
